How does this thing contact internet when power is lost.?
Why not just be a power source for a few hours so WiFi still works and my bearded dragon doesn’t die while I race home?
If the power continues remain off will it send a message every minute until it comes back on?
I want to use this connected to a Verizon WiFi hotspot on my boat - will it use up my monthly data, or only when it connects to send me an alert?

So far so good

Had some initial issues setting it up but that’s not uncommon because I use a vpn on my devices most of the time. Once I paused the vpn was able to set it up without any issue. I plugged it in to the GFCI circuit all my outdoor landscape lights are on . Unfortunately a refrigerator and a freezer were on it too and the dang thing was starting to trip every time it rains. I moved the appliances off the circuit but still want to know when it trips. It seems to work perfectly for that. It sends the sms and email within a minute after the GFCI trips. It helped me troubleshoot and I think I found what is causing it to trip but there are other iffy connections on this line so I’m glad Ive got it. So for now the best I can say is so far so good and working as advertised.

This device really works.

I live in a rural area and electricity is provided by an electrical co-op. We’re supposed to have smart meters that are supposed to notify us when the electricity goes out. However, they don’t work and after many calls to the Co Op I was not able to get any answers. I asked them wasn’t there a device that would notify me when electricity was out. They said they didn’t think any devices existed. Since I have Fiber Optics, I bought a universal power supply and got your device and it works perfectly. I just got a message yesterday that the electricity was out. It turns out it was a very large outage, and I was notified later by the Co Op. I can’t say enough about your product. It really works.

Great product!

Why did you pick this product vs others?:I picked this product because I needed a straightforward solution for our sump pump, which is on a GFI plug. A few weeks ago, the pump stopped working, not because of a power outage, but because the GFI had tripped. While we are well protected from power outages, a GFI issue is not something I had considered, and if we happened to be away and not hearing the alarm, disaster would have ensued. The MySpool Power Failure Detector was easy to set up, and extremely reliable in our testing. Very highly recommended for peace of mind. A+++

Hard to connect to WiFi No app. Bad website

I got two of these to alert me when the GFCI by my fridge tripped and my sump-pump lost power. I tried for hours to get either one of them to connect to my wifi. There is no app, so you have to go through their terrible website which is not very user-friendly. They also don't tell you that you need to subscribe to Amazon's AWS alert system (you get a generic looking request via email, but I didn't know what it was because it doesn't mention being tied to the device at all; I was reluctant to sign-up for an unknown subscription). I tried all their troubleshooting steps to get it to connect. I got it to connect only one time, then it immediately lost connection again. It did manage to send an alert to my email, but it took almost 5 minutes. I cannot have that kind of unreliability. Maybe others were able to get it to connect, but I could not. Beware.

Essential for Sol-Ark inverter users

It’s great. Does exactly what it should. Nice build quality. Comes with 3 AAA alkalines installed but apparently only uses them in outages. Smart. The only downside is that you’re spending $60 and hoping the company stays in business for as long as you need the alerts. It includes the subscription. Remove AC power from the USB adapter it’s plugged into and it fires off up to 2 SMS texts and as many as 5 email addresses. Then you can set up a distinctive alert on your phone to differentiate from the daily noise.This is a God-send as we have a solar and storage system yet don’t receive utility outage notifications. So power could be out and we be draining our battery and not know it. I have a second panel that is only powered from utility. So I put this on a circuit on that panel. Then I can make load decisions in an outage. Eg turn off things that will take the battery down quickly.

Does what it's supposed to

I'm always concerned about devices like this, especially after reading the reviews, but so far the My Spool Power Failure Detector works as expected. I just bought this 2 weeks ago and it works and I've had no issues since I installed it! I get email notices whenever the power goes off and come back on. (As I'm writing this, I don't think I get text alerts, so I might need to check my settings)Like any IoT device, the initial set up is 'finicky'. It took me a few attempts to get it connected to my network, mainly because my device (Google Pixel phone) wouldn't open the browser window needed to enter my WiFi credentials. Again, not MySpool's problem and exactly the same 'finicky' connection issue I have with all my other devices that require you to connect to via WiFi. (Note: you connect your phone to My Spool device via WiFi like connecting to any WiFi router, not Bluetooth, then you enter your home WiFi credentials, then it will disconnect from your phone and connects to your home WiFi router. Just keep trying, it does work!

Great for refrigerators and freezers

The My Spool Power Failure Detectors are a reliable and efficient product. We are an independent doctor's office that uses the power failure detectors to monitor power to our medication and vaccines refrigerators and freezers. They have added value to the practice and prevented loss of inventory.

Great product

Was looking for something to monitor the power in the rv. Finally found the perfect product. Have already been notified of a power failure after installing it less than a week ago. Great product.
